摘要: 针对大量无线射频识别(RFID)病毒暂时无有效防御措施的问题,参考经典SIRS传播模型,在均匀网络环境下提出用于分析和控制RFID病毒的RSIRS病毒传播模型。通过考虑直接免疫、免疫态直接转化为易感态、感染后转化为易感态等因素,使模型更符合病毒实际传播情况。对建立的方程组进行平衡点及平衡点稳定性分析,得出病毒传播的阈值及消亡条件。数值仿真验证了该模型的正确性。

Abstract: Aiming at fairness problem of Radio Frequency Identification(RFID) virus’ rapid growth and no effective defense issues, consulting the SIRS propagation model, this paper provides the RSIRS virus propagation model which is suit to RFID viruses based on equality network. RFID virus propagational theory is studied. RSIRS model considers these susceptible become recovery because anti-virus software, recovery become susceptible directly, infections become susceptible and so on, which suits virus practical propagation condition better. The equilibrium points and their stabilities of this model are analyzed through the model’s equations. Threshold and dead condition of viruses propagation are given. Numerical simulations are used to validate.
